In this episode we discuss the power narratives have to affect our beliefs and behaviors with Melanie C. Green, a psychologist who studies the persuasive power of fiction.

According to Nielsen, the TV ratings company, the average person in the United States watches about 34 hours of television a week. That’s 73 days a year. Over the course of a lifetime, the average American can expect to spend a full decade lost in the trance spell that only powerful narratives can cast over the human mind.

Is your state of mind from one situation to the next drastically altered by the state in which you live? According to cultural psychologists, yes it is.

Studies show that your thoughts, perceptions, emotions, and behaviors in response to a particular setting will reliably differ from those of others in that same setting depending on where you spent your childhood or even where you spent six years or more of your adult life.

On this episode of the You Are Not So Smart podcast, we explore cultural cognition and the psychological effects of the region you call home on the brain you call yours.

After the interview I try out a cinnamon chocolate cookie and read a bit of psychology news about how reading good books can make you more adept at reading faces.

In every episode, I read a bit of self delusion news and taste a cookie baked from a recipe sent in by a listener/reader. That listener/reader wins a signed copy of my new book, “You Are Now Less Dumb,” and I post the recipe on the YANSS Pinterest page. This episode’s winner is Tamar Levanoni who submitted a recipe for cinnamon chocolate cookies. Send your own recipes to david {at} youarenotsosmart.com.

In 2008, renowned programmer and essayist Paul Graham wrote a guide for citizens of cyberspace titled “How to Disagree.”

Ten years had passed since the invention of the comment section. Twitter was two years old. The world had spent nine months with the iPhone. To Graham it had become apparent that the Internet had permanently changed the paradigm of the written word, which was as he put it, “writers wrote and readers read.” Instead, he predicted the call and response model of the web was here to stay. People would add their perspectives to everything. Content had become and would forever be a conversation, he predicted, and that meant everyone would need to learn how to argue more efficiently because exposure to rampant bickering would soon become a big part of daily life.

The reason, explained Graham, was that when you agree with something you usually don’t have much to add, so most people tend only to respond in paragraph form when they disagree. Naturally then, more disagreements than agreements would soon begin to spawn, and they would reproduce at a much higher rate. The result would be an Internet that looked and seemed angry and polarized, which might then become a weird sort of self-fulfilling prophecy. He warned: “…there’s a danger that the increase in disagreement will make people angrier. Particularly online, where it’s easy to say things you’d never say face to face.”

A year after Graham wrote his essay, Facebook lowered the already low cost of agreeing to a single click of a “like” button. The disagreements he predicted began to stack upon each other and grow long enough to benefit from spell checking.

Today, everywhere you click online you can witness the roiling boil of response just as Graham divined, and you can see why he suggested we ought to learn how to disagree like civilized adults. Just bounce over to the Huffington Post and check out the comments under any story focused on politics. You’ll find an opinionated, angry human centipede snaking its way down the page. On YouTube, minutes-old comments float around underneath videos posted years ago, each one a fragment of an ongoing argument populated with thousands of participants eagerly punching keyboards in an attempt to prove his or her beliefs are sound. The discourse there has encouraged 13,000 people to download a browser extension that turns all comments into variations of the phrase, “Herp derp.”

So, here in the online world Graham warned us about, human beings seem to be getting into and spectating upon more arguments than ever before. Our beliefs are getting challenged every day. Our ideologies and political camps are regularly being raided. According to many experts, this is not a bad thing, just a new one. Will it change us? Sure. But it will probably change us for the better.

Our increased exposure to arguing also means increased exposure to the mental foibles and errors of logic and reasoning that so often appear when people square off in rhetorical combat. Arguing with ourselves and others has become a fascination. We are suddenly eager to buy books about irrationality because we see so much more of it in our daily lives than just a decade ago. There seems to be so much more motivated reasoning and self delusion in the world than ever before too, thanks to the natural imbalance of communication Paul Graham told us to expect. We all want to understand what is making all of us so unreasonable. That yearning has helped bring the wisdom of the skeptical movement closer to the mainstream and place books about the psychology of bias on bestseller lists.

A question we never really considered asking is now making our brains itch. Why do we argue? What purpose does it serve? Is all this bickering online helping or hurting us?

Science thankfully has something to say about these questions, and what it has to say may even help explain reason itself. That’s the subject we explore in this episode of the You Are Not So Smart Podcast.

My guests are:

Jeremy Sherman, an evolutionary epistemologist, which means he researches how humans evolved to make generalizations and draw conclusions from inconclusive data. At 24, he was an elder in the world’s largest hippie commune, but now he lectures at the Expression College for Digital Arts in Emeryville California and is a chief researcher at Berkely’s Consortium for Emergent Dynamics where he and others research how minds emerge from matter. He is now working on a book, “Doubt: A Natural History; A User’s Guide” and he blogs at Psychology Today.

Hugo Mercier is a researcher for the French National Center for Scientific Research who shook up both psychology and philosophy with a paper published in 2011 titled, “Why do humans reason? Arguments for an argumentative theory” (PDF) that proposed humans evolved reason to both produce and evaluate arguments. Respected and well-known names in psychology like Steven Pinker and Jonathan Haidt have both praised the paper as being one of the most important works in years on the science of rationality. You can find his website here.

After the long interview, as in every episode, I read a bit of self delusion news and taste a cookie baked from a recipe sent in by a listener/reader. That listener/reader wins a signed copy of my new book, You Are Now Less Dumb, and I post the recipe on the YANSS Pinterest page. This episode’s winner is Jaimie-Leigh Jonker of New Zealand who submitted a recipe for orange coconut chocolate chip cookies. Send your own recipes to david {at} youarenotsosmart.com.
